It’s tiny. I have it mounted on a micro indoor model airplane controlling the motor and one servo. Works fine. However, if more channels are required, then some sort of power bus will be required as there are only two tiny pads on the board for power. There are no pads for powering the servos, only the pwm outputs. Also, be careful of the board diagram. It is drawn such that you could presume that the reference was the pair of chips toward the bottom of the board. This is in fact backward. Take the antenna as reference and look for silkscreened labels (+ and -) beside the smt resistor that is positioned between the power pads and the +/- labelling.
